How to disable kernel messages (dmesg) Flooding on the console<\/p>\n

\n

Method. 1<\/u><\/h3>\n

Edit the syslog config file\u00a0\/etc\/rsyslog.conf<\/b> and do the following modification.<\/p>\n

#kern.* \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \/dev\/console<\/b>
\nUnhide and Modify the above line as below
\nkern.* \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \/dev\/null<\/b><\/p>\n

Restart the rsyslog service
\n#service rsyslog restart<\/b><\/p>\n

Method. 2<\/u><\/h3>\n

If the above method is not solving the problem, then try changing the dmesg log level.<\/p>\n

To see the current log level
\n#sysctl kernel.printk<\/b>
\n4<\/b>\u00a0\u00a0 \u00a0 \u00a0 4 \u00a0 \u00a0 \u00a0 1 \u00a0 \u00a0 \u00a0 7<\/p>\n

To Change the log level<\/p>\n

<\/div>\n
#dmesg -n (log level)<\/b><\/div>\n

#dmesg -n 1<\/b><\/p>\n

#sysctl kernel.printk<\/b>
\n1\u00a0<\/b>\u00a0 \u00a0 \u00a0 4 \u00a0 \u00a0 \u00a0 1 \u00a0 \u00a0 \u00a0 7To fix at each reboot, add the following line to \/etc\/rc.local<\/b> file
\ndmesg -n 1<\/b><\/div>\n<\/div>\n

Supported log levels (priorities):<\/u><\/b><\/h4>\n

0 – emerg – system is unusable
\n1 – alert – action must be taken immediately<\/b>
\n2 – \u00a0crit – critical conditions
\n3 – \u00a0 \u00a0 err – error conditions
\n4 – \u00a0 \u00a0warn – warning conditions
\n5 – \u00a0notice – normal but significant condition
\n6 – \u00a0 \u00a0info – informational
\n7 – \u00a0 debug – debug-level messages<\/p>\n","protected":false},"excerpt":{"rendered":"
